Outdoor escape game by Qula—not a physical escape room, but a self-guided puzzle route through Haarlem. There are 2 different routes in Haarlem. Haarlem is known for its location near the beach and many monuments. The City Trail leads players at their own pace through the city: on their smartphone they solve riddles and complete tasks that guide them from place to place, including Het Hofje van Bakenes, Vrouwen Gasthuys, Prinsenhof and Sint Bavokerk. It's an independent treasure hunt without a guide, with the team earning the most points winning.
